[Lp(a) and lipid order in a group of secondary school students selected according to their family anamnesis].

In this study we evaluated the several risk-factors, Lp(a) and lipids order, related to the family history for ischaemic cardiovascular disease (CHD) atherosclerotic cerebrovasculopathy and arterious hypertension, in a healthy adolescent group, to stress possible early and significant alteration of the lipids order and Lp(a); we also considered which of these parameters may be considered the risk factor most closely related to family history. We studies 130 healty high school students, mean age 16.5 +/- 5.5 years, selected in four groups related to the family history: the first one composed of 34 subjects with positive family history for CHD; the second one of 32 subjects with positive family history for cerebral infarction (CI); the third by 32 subjects with family history for arterial hypertension and the last group by 30 control subjects. Mean value of all variables considered was in the normality range. Lp(a) resulted in the normality range with the exception of the group with positive family history for CHD. Also the traditional risk factors (Total-Col., LDL/Col. and Triglycerides) were increased in this group. Besides the differences between the mean of Lp(a) and Total/Col. in the group with positive family history for CHD and in the control group were statistically significant. The results showed that Lp(a), even if it cannot replace the family history in the screening of coronary atherosclerotic disease, might be considered a risk marker of early atherosclerotic disease.
